Ingredo.app for PKU and phenylalanine
Ingredo.app flags phenylalanine sources on every product you scan and cites the EU labelling rule behind it. There is no profile to switch on yet.
Allergen profiles are a hard block, not a soft caution — a declared source turns the verdict to "avoid" outright, rather than nudging the score.
Where an ingredient cannot be verified, the result degrades to "couldn’t verify — check the label". A safety flag never silently becomes a pass.

Check the label
- Phenylalanine sources: aspartame (E951)

Common questions
Not yet. Aspartame carries a "phenylalanine source" flag on the ingredient list of every product you scan, with the EU labelling rule cited — but there is no profile to switch on, and a PKU diet needs far more than one additive checked.
No. Phenylalanine occurs naturally in all protein, and Ingredo.app does not calculate a phenylalanine load. This flag is only about declared aspartame.
